AAON, Inc. announced its zero degree cold climate air-source heat pump packaged rooftop unit is now available from 2-30 tons. This product line is a critical solution that meets the increasing demand for building decarbonization in cold climates. Traditional air-source heat pump products have limitations that prevent heating operation at low ambient temperatures.

With the optimization of variable speed compressors, variable speed outdoor fans, and advanced AAON controls, the zero degree cold climate air-source heat pump enhances compressorized heat pump heating application into a wide range of climate zones, down to 0°F. Research and development is already underway at AAON for expanding the product line into larger capacity equipment, as well as expanding the operating range down to even lower ambient temperatures.
